Had a look at it yesterday, but it's not that great either tbh, but thanks anyway!

I finished the pencil sketches of the Siemens SA22754 and now i'm creating the according parts in KiCad.

Hi folks, it's been a long time since i last posted something here.. But let me introduce to you my latest project: The process of creating clean Dragon32 schematics. The schematics online are more or less garbage, as they are very difficult to read, therefore a clean version (created with KiCad) co...

Good morning Dragon Folks! :) Today I will start the recreation of the PCB layout. Yesterday I made a DRC check and it was full of little errors (trace width and so on..) And when this is finished, the old question comes up again: How do we want to test it? I recently had the idea, if someone could ...

FOLKS!

I found the PCB files again.
This means, that we can go on with the clone project!!
I can give you more infos about it tonight..

Hi, i'm back.

But unfortunately i think i lost the PCB files..
so i have to do it again, but i will restart this project!

Stay tuned!

hi,

at the moment it's a little messy..private problems and school, but i still have the project going..

and then maybe someone would like to test it?
would be nice.

so long,

for the 4 most important suppliers: Reichelt, Farnell, Mouser and TME.eu.

Have a look and correct me if there are any mistakes.

looks very interesting..
wait, I've got a RaspBerry Pi too...

BTW; you've got a PM.

Fabian, welcome to the forums! What a beautiful project! Thank you, tormod! :) Do you have the original board, or are you basing it on the photos in the wiki? It's based on the photos in the wiki. You could use the black and white layouts to make a PCB, but the traces look ugly ;) So i started a ne...

Hi markjp,

first of all welcome to the Dragon Archive Forums

Regarding to the fact, that you have a green square you have a PAL Model. (please correct me if I'm wrong).

Could you make a photo of the motherboard of the Dragon and post it here?

Cheers,
Fabian
